I've written a simple application to encrypt an image (jpeg file) based on a password as a challenge to a mate of mine who reckons he's an ace hacker.I can encrypt the image no problem but when I try to save it using
[Code]...
I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
I tried this but does not work..

I have a problem when trying to save a picture box image ( I am using vb2008 express edition)When i load my windows form I create a folder called images and the current date (eg images 24062011) using the following code.
Code:
Dim fold As String = "images" & " " & Format(Now(), "ddMMyyyy")
If My.Computer.FileSystem.DirectoryExists("C:usersmickdesktop" & fold) Then
MsgBox(" file exists")
[code].....
this works fine and creates the folder on my desktop. I then load an image into a picturebox and try to save it using the following code which is where the problem starts.
Code:
Dim filename As String = Format(Now(), "ddMMyyyy")
Dim imagename As String = "image"
Dim fileext As String = Drawing.Imaging.ImageFormat.Bmp.ToString
[code].....
so my problem is why does the 1st statement give me the error as surely as I have declared that fold = the folder name then that path should be correct, as the program is set to save the image automatically, not using the savefiledialogue I don't want to have to manually type in the folder name every time I use the program.
I have tried to realign the image by down and right one pixel, but still only part of the first row and column are visible when zoomed.I can't find exactly what I'm looking for online.

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
This code shows me the preview of a webcam in a picture box. I want to know how to save a frame as a picture file.The code I'm currently using to save it (in the timer tick event) gives me the "Object reference not set to an instance of an object." error..Then I used a debug assert line and it gave me an error that basically says that there is no image in the picture box, while I can clearly see a picture in the picture box. Can anyone please help me write/edit the code to save it?
